THE LAST MILE
Almost finished.
Still going in circles.
The interface is there. The app doesn’t work.
When asking your AI again isn’t getting you further,
start by understanding the code.
Fix one thing.
Connected, you thought.
But nothing happens.
Authentication, payments, APIs or the database aren’t fully connected. The features behind the interface don’t work.
Works on your machine.
Won’t go live.
Build errors and environment settings block your release. You’re unsure what else to check before publishing.
CLARITY BEFORE CODE
Before another fix,
see the whole picture.
Start with runtime and configuration checks, then go deeper when needed. Paid plans add production follow-up, with prevention available on Pro and above.

HOW IT WORKS
From a problem you’re stuck with
to a path you can follow.
No polished specification needed to get started.
Just your project, and what isn’t working.
STEP 01
Share your code. Explain the problem.
Start with attached logs on Free. Paid plans connect repositories and hosting to share the state of your project.
Attached logs / repositories / hostingSTEP 02
Understand what to fix first.
Light checks cover builds, tests, startup and configuration. Pro and above add deeper diagnosis with exploration agents and fault injection.
Light checks / deep diagnosis (Pro and above)STEP 03
Work with AI. Bring in a professional when needed.
Use AI consultation to work through fixes. Paid plans check whether changes reach production. Premium engineer consulting is an optional extra on Standard and above.
AI consultation / follow-up / optional Premium consultingSHARE WHAT MATTERS
Start with the data
you already have.
Attach logs. Connect your development environment.
The planned sharing approach depends
on your plan and organization’s needs.

Light checks
Deterministic tools and a lab for builds, tests, startup checks and configuration invariants.
Deep diagnosis
Diagnosis using exploration agents and fault injection: twice monthly on Pro, seven times monthly on VIP.
Follow-up & prevention
Standard and above check whether a fix reaches production. Pro and VIP also generate AI rules and CI for prevention.

SECURITY ADD-ON
Security tool diagnosis
Coming soonOptional on Standard and above / included in Enterprise
From mapping the attack surface to lab simulations and rechecks after remediation.
- Attack surface mapping & security invariants
Check required security properties covering IDOR, SSRF, webhooks and injection into AI features.
- Attack simulation in an isolated lab
Simulated attacks run in the lab, never against production.
- Scan the entire Git history for secrets
Scan the entire Git history, not only the current code.
- Dependency reachability & ongoing monitoring
Determine whether vulnerable dependencies are actually called and continuously monitor for newly disclosed vulnerabilities.
- Recheck after fixes
Run the checks again after remediation.
- Two reports for different audiences
A technical report and a handover version with attack procedures withheld.
Add-on price: TBD · Coming soon
HUMAN CONSULTATION

Professional engineers who pass
a pre-registration test
The planned registration process requires engineers to pass a test before handling consultations.
This is a separate service from the AI consultation allowance in your monthly plan. Consultation duration and detailed service scope are TBD.

SECURITY ADVISOR
Security advisor consultation
An optional service for discussing security questions and how to address findings with an advisor. Scope, eligible plans and pricing will be announced when ready.
GOOD TO KNOW
A few things
you might be wondering.
Do I need to be an engineer?
The service is conceived for non-engineer founders, planners and beginner engineers building with AI. It aims to explain the state of a project and the work needed to move forward.
Will the diagnosis automatically fix everything?
AI consultation and diagnosis help identify causes and a repair approach. Paid plans include checking whether a fix reaches production. Premium consulting is a separate optional service on Standard and above, with pricing TBD. Resolving every issue or completing every project is not guaranteed.
How do light checks, deep diagnosis and security diagnosis differ?
Light checks use deterministic tools and an isolated lab for builds, tests, startup checks and configuration invariants. Deep diagnosis uses exploration agents and fault injection, with monthly allowances on Pro and VIP. Security diagnosis is an add-on for Standard and above and is included in Enterprise.
Can I upload my code to try it?
This LP is a design and user-flow prototype. The free-check buttons open an interactive demo using sample data. GitHub integration, uploads, AI analysis and payments are not connected.
How is Enterprise different from individual plans?
Individual plans have set monthly prices and allowances. Enterprise is configured for a development team, with custom usage, dedicated or customer-AWS deployment, SSO, audit logs, SLA, inference region selection and GitHub Enterprise Server connectivity. Security diagnosis is included.
What are the data retention, deletion and AI training policies?
Shared code, logs and consultation content are not to be used to train general-purpose AI models. External processors, processing regions, retention and deletion details will be explained before the service starts. See the Privacy Policy (Japanese). This introduction site does not accept real code or logs.
Are the effort estimates final quotes?
Effort and cost would be indicative estimates to support a decision. The actual work depends on the code and investigation findings. Diagnosis samples on this website are based on examples in the project brief.
